Inbuilt Lithium Battery MPPT Solar Inverter 1kW

The Luxntek 1kW inbuilt lithium battery MPPT solar inverter is an all-in-one solar power backup system that combines a 1000W pure sine wave inverter, 60A MPPT solar charge controller, and 12.8V 100Ah LiFePO4 lithium battery in a single unit. It is designed for homes, offices, shops, and small solar backup applications.

The inverter has an integrated 12.8V 100Ah LiFePO4 lithium battery, providing a nominal energy capacity of 1280Wh (1.28kWh).

Yes. This model has an inbuilt 12.8V 100Ah LiFePO4 lithium battery, so a separate external battery bank is not required for normal operation.

The system uses a LiFePO4 (Lithium Iron Phosphate) battery. LiFePO4 technology is commonly selected for solar energy storage because of its long cycle life, stable chemistry, and suitability for repeated charging and discharging.

The inverter provides up to 1000W continuous output power. The actual load that can be connected should remain within the inverter's rated capacity, while appliances with high starting or surge currents should be evaluated separately.

The Luxntek 1kW inverter provides DSP-based pure sine wave AC output at approximately 220V AC ±5% and 50Hz ±0.3%. This makes it suitable for compatible household appliances, electronics, lighting, fans, computers, and other AC loads.

MPPT stands for Maximum Power Point Tracking. An MPPT solar charge controller continuously adjusts the solar operating point to extract available power efficiently from the connected solar panels.

The built-in solar charge controller is rated at 60A MPPT charging current, with the charging current configurable according to the system requirements and battery specifications.

The specified MPPT operating voltage range is 30V to 140V DC, with a maximum PV open-circuit voltage of 140V DC.

The specified maximum solar PV power is 1200W. The solar panel configuration must also remain within the inverter's voltage and current limits.

A recommended example is 3 × 400W solar panels in series, where a panel with approximately 46V Voc gives a combined open-circuit voltage of about 138V.

The actual panel configuration should always be checked against the panel's Voc, Vmp, temperature coefficient, and the inverter's 140V maximum PV Voc limit.

Yes. The inverter has an integrated MPPT solar charge controller. The solar array should be connected according to the specified PV voltage, current, and maximum Voc limits.

Yes. The integrated lithium battery can provide backup power even when solar generation is unavailable, subject to the battery's available energy and inverter load.

Backup time depends on the connected load, inverter efficiency, battery state of charge, and operating conditions.

As a simple energy estimate:

Backup time ≈ 1280Wh × usable battery fraction × inverter efficiency ÷ load in watts

For example, a lower-power load will generally operate for considerably longer than a load close to the inverter's 1000W rating.

It may be suitable for a compatible refrigerator, but the refrigerator's starting/surge power must be checked. Compressor-based appliances can require substantially more power during startup than their normal running consumption.

Yes, provided the combined running load and startup/surge requirements remain within the inverter's rated capacity. The pure sine wave output is suitable for many common electronic and household loads.

Yes. Solar energy is processed through the built-in 60A MPPT solar charge controller to charge the integrated LiFePO4 battery.

Yes. The specifications list a 15A grid charging current. The AC input and charging operation should be used within the specified electrical limits.

The integrated charging system manages the battery charging process according to the configured battery and charging parameters. The system is designed to combine solar charging, battery storage and inverter operation in one unit.

The system includes multiple protection functions. The specified protections include low-battery protection, overload protection, short-circuit protection, over-temperature protection, PV reverse-polarity protection, PV over-voltage protection, MPPT overload protection, and battery reverse-polarity protection.
